I was taking a hot bath, when I was done and got up to dry off, I closed my eyes and suddenly got very dizzy, like the room was spinning, and my heart began to beat like it was going to come out of my chest. I stumbled out of the tub and had to sit down. I got up again slowly, had the same two things happen again but my eyes were open and my vision blurred. This went on for about 15 seconds. When it settled, I started feeling nauseous. I am 22, 200lbs, no medical diagnosis, but did have a hole in my heart (that naturally closed) when I was born.
